PROCESS FOR PRODUCING AMINOPHOSPHONIC ACID DERIVATIVE

摘要

To present a reaction system that efficiently catalyzes an enantio selective asymmetric nucleophilic addition reaction of an ±-iminophosphonic acid ester. An optically active ±-amino-³-oxophosphonic acid derivative is produced through an asymmetric addition reaction of an ±-iminophosphonic acid ester and a nucleophilic agent (for example, a silyl enol ether).
